ANSYS

Computer-aided engineering (CAE) simulations enable engineers to design more virtual prototypes, thereby spending less time building physical ones. More iterations lead to a higher quality product. GPUs further improve productivity by accelerating simulations, thus helping reduce the product development times resulting in a competitive advantage for businesses.

ANSYS® and NVIDIA® work collaboratively to ensure the fastest performance for simulations running on ANSYS parallel software. NVIDIA GPUs support the following products:

Mechanical: ANSYS® Mechanical® 15.0 supports a full feature set including use on multiple GPUs.

Accelerating ANSYS simulations with NVIDIA GPUs have never been easier. In version 15.0, all HPC license products (HPC, HPC packs, HPC workgroups, and HPC enterprise) enable GPUs. Specifically, each GPU socket is treated the same as a single CPU core with respect to license requirements. As a result, more simulations are possible with existing HPC licenses combined with NVIDIA GPUs for dramatically increasing simulation productivity.

"ANSYS Mechanical users can get higher throughput on large models with an NVIDIA Tesla K40 in their workstations. Models as large as 12M degrees of freedom can be accelerated with a single K40 and provide 2X performance gains over just CPUs."

ANSYS® Fluent® 15.0 now features multi-GPU support to deliver higher productivity in CFD simulations. This performance enhancement is the result of innovative GPU-accelerated solvers developed by NVIDIA in collaboration with ANSYS (called AmgX) and the new license scheme in ANSYS 15.0. The current implementation in Fluent 15.0 accelerates pressure-based coupled flow solver, speeding up the flow portion of CFD simulations. This benefit can simply be unlocked by adding Tesla K20, Tesla K20X or Tesla K40 GPUs to any existing HPC infrastructure. It is designed to run across multiple nodes with multiple GPUs in a cluster configuration, just like CPU systems. Please refer to the NVIDIA application note on Accelerating ANSYS Fluent 15.0 Using NVIDIA GPUs for more details on using GPUs in Fluent 15.0.

Recommended Professional Products

The powerful GPU computing capabilities in ANSYS was developed on NVIDIA Professional GPUs. A CUDA-capable NVIDIA GPU (CUDA v4.2 or above) should be used. Suggested GPUs from the NVIDIA® Tesla® Kepler™ product family or NVIDIA® Quadro® Kepler product family are recommended.

NVIDIA GPU computing products are designed to deliver the highest computational performance to accelerate computations in ANSYS software.
